The anti-UAV system comprises: a plurality of laser devices configured to generate a plurality of laser beams at a plurality of different wavelengths; a coarse wavelength division multiplexing (CWDM) combiner configured to combine the plurality of laser beams from the plurality of laser devices into a combined laser beam; and a tracking device configured to detect a UAV. The anti-UAV computing platform is configured to: detect, using the tracking device, an object within range of the tracking device; and based on detecting the object, direct, using the anti-UAV system, the combined laser beam from the CWDM combiner onto the detected object.

A weapons system with at least two HEL effectors, which have at least one beam guidance system, the use of only one laser source or one pump source for the at least two HEL effectors is provided. The beam guidance systems of the HEL effectors resort to the common laser source or common pump source. An optical link of the common laser source or of the common pump source with the beam guidance system, be it direct or indirect, is implemented by means of at least one optical switching unit, and so at least one functional, complete HEL effector of the weapons system is provided to defend against threats.

At a designated range an ultra-short pulse laser beam collapses focusing its power and thereby creating a plasma. A range specific thermal plasma is formed from a pulsed laser configured to produce a pulsed wavefront at a peak power. The peak power of the wavefront exceeds a self-focusing critical power level. An optical wavefront controlling element having one or more optical lens manipulates the pulsed wavefront based on a ratio of the peak power to the self-focusing critical power level, and an atmospheric condition, initiating whole beam collapse at the designated range.

The present invention relates to an apparatus, detachably mountable to the external surface of an aircraft. More specifically, the present invention relates to a fully self-contained apparatus comprising an electrical device, such as a

Directed Energy Weapon (DEW), and a corresponding thermal management system and power supply.

An apparatus includes a deformable mirror. The deformable mirror includes a reflective surface configured to reflect a high-energy laser (HEL) beam and to focus the HEL beam on a target. The deformable mirror also includes multiple actuators configured to adjust a shape of the reflective surface in order to maintain focus of the

HEL beam on the target over a specified range of distances between the deformable mirror and the target. At least one portion of the reflective surface is configured to be adjusted by the actuators and obtain convex, flat, and concave shapes.
